🚨🦟 West Nile Virus in horses detected in Belgium— what horse owners should know
West Nile Virus (WNV) is a mosquito-borne disease that can affect horses and, in some cases, cause serious neurological disease.
🦠 How does it spread?
Horses become infected through the bite of an infected mosquito. Horses do not transmit the virus directly to other horses or to people
🐴 What should you look out for?
Most infected horses show no signs, but some can develop neurological symptoms such as:
• Fever
• Muscle weakness
• Ataxia or difficulty walking
• Tremors or twitching
• Depression or unusual behaviour
• Recumbency (being unable to stand)
⚠️ Neurological signs in a horse should always be taken seriously. Contact your veterinarian promptly if you notice anything unusual.
🛡️ Prevention matters
Reducing mosquito exposure can help lower the risk:
• Remove standing water where mosquitoes can breed
• Keep horses indoors during peak mosquito activity where practical
• Use appropriate mosquito repellents
• Consider vaccination— talk to your veterinarian about whether it is recommended for your horse
As veterinarians, we’re here to help you assess the risks in your area and choose the best prevention strategy for your horse. ❤️🐎
Stay informed, stay vigilant, and protect your horses from mosquito-borne disease.
